In Farm Mechanization, a tractor is an inevitable machine that generates power which can be utilized in number of ways. Common set of important implements are a need for a farmer right from tillage to harvesting. Following are the common useful implements/attachments.
Power Harrows belong to tillage equipment category that are driven by the power take-off shaft of a tractor and best suited for hard and hard-clay soil conditions.
A power harrow functions typically the way the egg-beater does the stirring action. This breaks up the soil lumps / clods after the land has been tilled. The fine soil is forced to the seedbed level and the small clods and compost remain on the surface to create a perfect seed-bed. They can be used as secondary tillage after ploughing or subsoiling and also can be used to till the most compacted earth in a single pass. As they do not disturb the soild layers and as they help maintain the soil’s natural composition, structure and biodiversity, the power harrows are very vital for a farmer.
To minimize soil compaction by the passes of tractor, when combined with seed drill a farmer can achieve soil cultivation and seeding in a single pass.
Mouldboard plough is also called turn-plough. Soil inversion is achieved by ploughing with a mouldboard plough. This type of ploughing helps overcome non-wetting soils, burying herbicide resistant weeds, removing soil compaction, increased nitrogen mineralization and improved nutrient access. In due course of the time, the top-soil becomes water repellent and by using a mouldboard plough brings the subsoil to the surface, which is not water repellent. At the same time the top-soil is buried to the depths where it is fully wet and inhabited with the crop roots. It is also a soil renovation method if used sparingly at right intervals based on the soil types.
A mouldboard plough’s coulter cuts down into the soil and the share cuts horizontally from the previous furrow to the vertical cut. This releases a rectangular strip of sod and places it upside down. The gap in the ground where the soil has been lifted is called a furrow.
